Description

Technical Field

[0001] This utility model belongs to the field of air column smoke machines, specifically, it relates to a tornado-type smoke enhancement device. Background Technology

[0002] Air column smoke machines are special effects equipment commonly used in stage performances, celebrations, and film and television shooting. Their main function is to spray columnar smoke to create a three-dimensional and impactful smoke effect. Unlike the diffuse smoke produced by ordinary smoke machines, the smoke sprayed by air column smoke machines is columnar, bundled, or in a specific shape. The direction and shape of the smoke can be precisely controlled to enhance the visual depth and atmosphere of the scene. However, existing air column smoke machine devices have poor flexibility in automatically adjusting the direction and angle of the air column, which cannot meet the needs of complex stage special effects environments, reduces the atmosphere of the stage, and results in poor practicality of the device.

[0003] Chinese patent CN215841613U discloses a stage special effects air column smoke machine. This device uses a first motor to drive a set of rotating shafts to rotate, causing the upper housing to rotate back and forth between two sets of side plates. This causes the upper housing to swing back and forth at the output end of the air column spraying device. By activating a second motor, a worm gear is driven to rotate, which in turn drives a turntable to rotate left and right. This allows the upper housing to swing back and forth in conjunction with the turntable to rotate left and right, thus adjusting the output end of the air column spraying device at multiple angles and improving the flexibility of air column spraying angle adjustment. However, in use, the smoke sprayed by this device is a straight column shape, which has poor visual appeal and low spray intensity, thereby reducing the effectiveness of the device. In view of this, this utility model is hereby proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a tornado-type smoke enhancement device, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A tornado-style smoke enhancement device includes: an air column smoke machine body, which has a smoke generator inside. The top of the air column smoke machine body has a through-hole. A vortex fan is fixedly installed in the air column smoke machine body relative to the smoke generator through a mounting bracket. A smoke flow pipe is connected between the inlet end of the vortex fan and the outlet of the smoke generator. A controller is provided outside the air column smoke machine body. The injection pipe is fixedly installed on the mounting bracket. One end of the injection pipe is connected to the outlet end of the vortex blower, and the other end is connected to the injection port.

[0006] Optionally, a spiral guide groove is embedded in the injection pipe along its height direction, and the spiral direction of the spiral guide groove is the same as the rotation direction of the fan blades of the vortex blower.

[0007] Optionally, a connecting pipe is connected between the injection pipe and the injection port, and the connecting pipe is a truncated pyramidal structure with a gradually increasing cross-sectional area from one end connected to the injection port to the other end.

[0008] Optionally, a spray bucket is fixedly installed around the spray nozzle on the top of the air column smoke hood body. The spray bucket is a hollow structure with openings at both ends. The spray bucket is a funnel-shaped structure with a gradually increasing cross-sectional area from one end connected to the air column smoke hood body to the other end.

[0009] Optionally, the smoke flow pipe is a funnel-shaped structure with a gradually decreasing cross-sectional area from the end connected to the smoke generator to the end connected to the vortex fan. A spiral guide plate in a spiral shape is fixedly installed on the inner wall of the smoke flow pipe along its height direction. The spiral direction of the spiral guide plate is the same as the rotation direction of the vortex fan blades.

[0010] Optionally, an air pump is fixedly installed inside the air column smoke hood body. The air pump is connected to the smoke flow pipe through an air delivery pipe, and the air outlet of the air delivery pipe is arranged in the spiral direction of the spiral guide plate.

[0011] Optionally, a connecting hopper is connected between the smoke flow pipe and the vortex fan. The connecting hopper is a funnel-shaped structure with a gradually increasing cross-sectional area from one end connected to the smoke flow pipe to the other end.

[0012] Optionally, a maintenance plate is detachably connected to the main body of the air column smoke hood.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: 1. By setting up a vortex fan, and by cooperating with the smoke generator, the smoke can be concentrated and sprayed out to form a smoke column with a certain height and intensity, simulating the effect of a tornado. This greatly enhances the visual effect of the smoke spray. Compared with straight column smoke, the tornado-shaped smoke pattern is more dynamic and shocking, which can greatly improve the aesthetics and usability of the device. 2. By setting up a spiral guide channel, the smoke airflow is rotated, which enhances the smoke gathering effect, reduces the diffusion of smoke during the spraying process, makes the smoke column more compact, and also helps to increase the spraying height of the smoke, making it more similar to the shape of a real tornado and enhancing the visual effect. 3. By incorporating a spiral guide plate and an air pump, the combination of the spiral guide plate and the air pump can improve the efficiency of smoke delivery and give the smoke a certain rotational state before it enters the vortex blower. This allows the vortex blower to better accelerate and pressurize the smoke, further enhancing the subsequent smoke jetting effect, making the smoke column more compact and the jetting height higher.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Please see Figures 1-6As shown, this embodiment provides a tornado-type smoke enhancement device, including an air column smoke machine body 1, which has a smoke generator 6 inside. A spray port 3 is provided through the top of the air column smoke machine body 1. A vortex fan 12 is fixedly installed in the air column smoke machine body 1 relative to the smoke generator 6 through a mounting bracket 11. A smoke flow pipe 7 is connected between the inlet end of the vortex fan 12 and the outlet end of the smoke generator 6. A controller 2 and a spray pipe 10 are provided outside the air column smoke machine body 1. The spray pipe 10 is fixedly installed on the mounting bracket 11. One end of the spray pipe 10 is connected to the outlet end of the vortex fan 12, and the other end is connected to the spray port 3.

[0020] Specifically, the smoke generator 6 first produces smoke, which enters the vortex fan 12 through the smoke flow pipe 7. Under the powerful airflow generated by the vortex fan 12, the smoke is engulfed and accelerated. At the same time, the unique rotational characteristics of the vortex fan 12 give the smoke the power to rotate. Subsequently, the rotating smoke is further guided and constrained through the injection pipe 10, and finally powerfully ejected from the injection port 3 in a tornado-like shape. Through the cooperation of the vortex fan 12 and the smoke generator 6, the smoke can be concentrated and ejected to form a smoke column with a certain height and intensity, simulating the effect of a tornado. This greatly enhances the visual effect of the smoke ejection. Compared with straight column smoke, the tornado-like smoke shape is more dynamic and shocking, which can greatly improve the aesthetics and usability of the device.

[0021] It should be noted that in this embodiment, the working principle and structure of the smoke generator 6 can refer to the structure of the existing air column smoke machine, which is the prior art; secondly, the mounting bracket 11 serves to fix the vortex fan 12 and ensure its stability during operation; the connection between the smoke flow pipe 7 and the injection pipe 10 and the vortex fan 12 must be sealed to prevent smoke leakage from affecting the effect.

[0022] In this embodiment, as Figure 6As shown, a spiral guide groove 16 is embedded in the jet pipe 10 along its height direction. The spiral direction of the spiral guide groove 16 is the same as the rotation direction of the fan blades of the vortex blower 12. Specifically, when the smoke, which has been accelerated by the vortex blower 12 and has a rotational tendency, enters the jet pipe 10, the spiral guide groove 16 plays an important guiding and strengthening role. Since its spiral structure is consistent with the initial rotation direction of the smoke, the smoke will be continuously guided by the spiral guide groove 16 as it flows along the jet pipe 10, making the rotation of the smoke more stable and orderly. This design brings many beneficial effects. On the one hand, it enhances the rotation intensity of the smoke, making the tornado shape formed by the smoke ejected from the jet nozzle 3 more compact and obvious, and enhancing the visual impact. On the other hand, the stable and orderly rotation helps the smoke to remain concentrated during the jetting process, reducing lateral diffusion, thereby enabling the smoke to be ejected further, further enhancing the jetting intensity and coverage of the smoke, and greatly improving the performance of the device.

[0023] In this embodiment, as Figures 2 to 6 As shown, a connecting pipe 13 connects the spray pipe 10 and the spray nozzle 3. The connecting pipe 13 is a truncated structure with a gradually increasing cross-sectional area from one end connected to the spray nozzle 3 to the other end. Specifically, the connecting pipe 13 improves the spraying effect of the smoke, allowing the smoke to be sprayed out from the spray nozzle 3 more concentratedly, thereby enhancing the realism of the tornado effect.

[0024] In this embodiment, as Figures 1 to 6 As shown, a jet bucket 4 is fixedly installed around the jet nozzle 3 on the top of the air column smoke hood body 1. The jet bucket 4 is a hollow structure with openings at both ends. The jet bucket 4 is a funnel-shaped structure with a gradually increasing cross-sectional area from the end connected to the air column smoke hood body 1 to the other end. Specifically, the design of the jet bucket 4 can significantly enhance the visual effect of the smoke, making it more in line with the appearance of a tornado. At the same time, the funnel-shaped structure helps to better concentrate the smoke in the central area, reduce the loss of smoke to the surrounding areas, improve the utilization rate of smoke, and allow viewers to see a more obvious and realistic tornado smoke effect. It should be noted that the size of the jet bucket 4 needs to be determined according to the overall size of the device and the usage scenario. A larger jet bucket 4 is suitable for use in open spaces to create a more spectacular effect, but it will increase the size and cost of the device.

[0025] In this embodiment, as Figures 2 to 5As shown, the smoke flow pipe 7 is a funnel-shaped structure with a gradually decreasing cross-sectional area from the end connected to the smoke generator 6 to the end connected to the vortex fan 12. A spiral guide plate 15 is fixedly installed on the inner wall of the smoke flow pipe 7 along its height direction. The spiral direction of the spiral guide plate 15 is the same as the rotation direction of the vortex fan 12 blades. An air pump 9 is fixedly installed inside the air column smoke machine body 1. The air pump 9 is connected to the smoke flow pipe 7 through an air supply pipe 8. The outlet of the air supply pipe 8 is oriented towards the spiral direction of the spiral guide plate 15. Specifically, the smoke generated by the smoke generator 6 enters the smoke flow pipe 7. Due to the funnel-shaped structure of the pipe, the smoke is gradually gathered and accelerated, while the spiral guide plate 15 guides the smoke flow. The smoke airflow forms a spiral motion. As the cross-sectional area of ​​the pipe decreases, the speed and density of the smoke airflow continuously increase, entering the vortex blower 12 with higher speed and concentration. At the same time, the air pump 9 delivers gas into the smoke flow pipe 7 through the air supply pipe 8. The air outlet faces the spiral direction of the spiral guide plate 15. After the gas is ejected, it merges with the smoke airflow, pushing the smoke to rotate and rise faster along the spiral guide plate 15. This also increases the pressure and speed of the smoke airflow, further enhancing the rotation effect and flow speed of the smoke. This allows the smoke to enter the vortex blower 12 more quickly through the smoke flow pipe 7, which helps to improve the smoke injection efficiency and injection height of the entire device, making the tornado smoke effect more obvious.

[0026] In this embodiment, as Figure 2 and Figure 3 As shown, a connecting hopper 14 connects the smoke flow pipe 7 and the vortex blower 12. The connecting hopper 14 is a funnel-shaped structure with a gradually increasing cross-sectional area from one end connected to the smoke flow pipe 7 to the other. Specifically, the connecting hopper 14 helps reduce the impact and turbulence of the smoke airflow when it enters the vortex blower 12, enabling the vortex blower 12 to accelerate and pressurize the smoke more efficiently, thus improving the overall performance of the device. It can also further adjust the shape of the smoke airflow to better suit the working requirements of the vortex blower 12, thereby improving the smoke jetting effect.

[0027] In this embodiment, as Figure 1 As shown, a maintenance plate 5 is detachably connected to the main body 1 of the air column range hood.

[0028] Furthermore, in this embodiment, the controller 2 is used to control the electrical components inside the air column smoke machine body 1, such as the air pump 9, the vortex fan 12, and the smoke generator 6. Its wiring installation method and working principle are existing technologies. Secondly, the structure and working principle of the vortex fan 12 and the air pump 9 are existing technologies and will not be described here.

[0029] Working principle: After being activated by controller 2, the smoke generator 6 inside the main body 1 of the air column smoke hood begins to work, producing smoke. The smoke first enters the smoke flow pipe 7, which has a funnel-shaped structure with a wide inlet and a narrow outlet. Utilizing the Venturi effect, the smoke flow rate is naturally accelerated. The spiral guide plate 15 on its inner wall (which rotates in the same direction as the vortex fan 12) guides the smoke to flow in a spiral direction, initially giving the smoke rotational kinetic energy. At the same time, controller 2 controls the air pump 9 to spray air into the smoke flow pipe 7 through the air supply pipe 8, with the air outlet facing the spiral direction of the spiral guide plate 15, further enhancing the rotational intensity and flow rate of the smoke and preventing the smoke from stagnating in the flow. Smoke that has been retained in the smoke flow pipe 7 and accelerated through the smoke flow pipe 7 enters the vortex blower 12 through the connecting hopper 14. The connecting hopper 14 has a funnel-shaped structure with a narrow inlet and a wide outlet, which smoothly transitions the smoke from the "contracting flow" of the smoke flow pipe 7 to the inlet of the vortex blower 12, reducing airflow impact and resistance loss, and ensuring that the vortex blower 12 efficiently draws in smoke. After the vortex blower 12 starts, it uses high-speed rotating blades to perform secondary compression and acceleration of the smoke. At the same time, because the direction of the blades is consistent with the initial rotation direction of the smoke, it further enhances the spiral motion of the smoke, giving the smoke stronger kinetic energy and rotational inertia. Subsequently, the smoke flows from the vortex... The smoke enters the jet pipe 10 from the outlet of the vortex blower 12. The spiral guide groove 16 inside the jet pipe 10 rotates in the same direction as the blades of the vortex blower 12, continuously guiding the smoke to flow along the spiral trajectory. This prevents the smoke from dissipating due to turbulence within the pipe, ensuring that the smoke maintains a "tornado-like" spiral structure. The spiral smoke then enters the connecting pipe 13 through the jet pipe 10 and into the jet bucket 4. The jet bucket 4 guides the spiral smoke to diffuse upwards along the funnel wall as it is ejected, maintaining the rotating shape (enhancing the "tornado" visual effect) and increasing the jet range and height through an increasing area design. Finally, the smoke is ejected in a high-intensity, spiraling upward shape, replacing the traditional... The straight column shape significantly enhances the visual impact. The controller 2 coordinates the operating parameters (such as speed and power) of the smoke generator 6, vortex fan 12, and air pump 9 to ensure matching of each component. The maintenance plate 5 can be disassembled at any time for easy maintenance of internal components (such as fans and pipes), ensuring long-term stable operation of the equipment. The overall structure and operation steps are simple. Through the synergistic effect of the spiral guide plate 15 and spiral guide groove 16, the smoke maintains a spiral motion throughout the process, ultimately forming a "tornado-like" rotating shape, replacing the monotonous straight column shape. The visual sense of layering and dynamism is greatly enhanced, while the spray intensity and range are increased, improving the overall usage effect.
